The black hole closest to Earth shone in a strange way

The only thing most people know about black holes is that they are dark entities, but the nearest hole on the planet has violated it, having observed a glowing, brighter hole that at any other time in its history, according to the British website "Metro"..

The black holes are so dense that the light can not move so fast to escape the high density of the hole, which always makes them dark. However, they can also produce a strange glow in the right conditions..

For example, black holes are often surrounded by gas and other glossy materials because of friction and gravity forces..

Here is a timelapse of images of more than 2.5 hours from May coming from @keckobservatory of the supermassive black hole Sgr A *. The black hole is still variable, but it was the brightest we have seen in the infrared until now. It was probably even brighter before we started watching tonight! pic.twitter.com/MwXioZ7twV

It is this phenomenon that allowed astronomers to take the first picture of a black hole earlier this year, which showed a shiny disc surrounding a dark nucleus..

A team from the University of California discovered a huge hole in the center of the world's largest galaxy, the Milky Way, 75 times brighter than usual. Scientists say the behavior can not yet be fully explained..

Scientists say the change is probably due to an increase in the amount of gas absorbed into the black hole.
